Admont, pretender Duke of Tristin, bastard son of Marquis Laborn. He claimed to have many enemies, and for a time, the people truly believed him, rallying behind him in his efforts to rid the duchy of witches and conspirators."

Pitchwoods: You must go through the jump-portion and then reach the very bottom, and go all the way to the right.

Carsejaw's attack in which he raises his arms and spawns blades from the ground is very similar to the Dark Souls 1 spell "Gravelord Greatsword Dance" in which the player will summon multiple swords from the ground around them, each one appearing identical to the swords of Gravelord Nito but with a red hue. Sadly, while Carsejaw has this attack, there is no spell that the player can acquire that has a similar function.

Holy slaughters him and if you have anything that hits hard then he can be dead in just a few swings. If you aren't going big weapons then just take a few swings when he does his slow combo and watch out for his blades from the ground. He's not too fast and the sanctuary is right next to him so he's not a major threat.
